IE8 results in "Error: 'JSON' is undefined"

Hi there,

We end up with an error "Error: 'JSON' is undefined" when accessing pages using telerik controls in IE8.
It is quite new when migrating to IE8 (after some security hotfix?) and the compatibility mode does not help...
Trying the last version of Telerik controls does not help neither...

Do someone face similar issue and can give us some hint there?

Regards,
David

Need to pass updated values after Edit Form is closed

I have a Radgrid using automatic Update, and a custom Edit Form template. I need to pass all the values of an edited row so I can populate an email that will be sent to users from the code-behind. Using the code below that I have cobbled together from various posts, I can get all the row's current values, but not the updated values using the ItemUpdated event. Is there another event I can use, or different code to obtain Updated values for that row after my Edit Form is closed and database updated? I am new to this, so code examples are helpful. Thanks!

C#

public void RadGrid1_ItemUpdated(object sender, GridUpdatedEventArgs e)

{

GridEditFormItem item = (GridEditFormItem)e.Item;

GridDataItem parentItem = (GridDataItem)item.ParentItem;

string emailFlag = parentItem["EmailToSalesFlag"].Text;

{

if (emailFlag == "true");

string SU = parentItem["StockUnit"].Text;

string Make = parentItem["Make"].Text;

string Model = parentItem["Model"].Text;

string Description = parentItem["Description"].Text;

string Type = parentItem["Type"].Text;

string CustName = parentItem["CustName"].Text;

string Salesperson = parentItem["Salesperson"].Text;

string RecDate = parentItem["Rec_Date"].Text;

string InvDate = parentItem["Inv_Date"].Text;

string SpiffProg = parentItem["SpiffProg"].Text;

string SpiffAmt = parentItem["SpiffAmt"].Text;

string Notes = parentItem["Notes"].Text;

string Approved = parentItem["Approved"].Text;

string MgrNotes = parentItem["MgrNotes"].Text;

string Email = parentItem["Email"].Text;

//Populate HTML email Body

PopulateBody(SU, Make, Model, Description, Type, CustName, Salesperson, RecDate, InvDate, SpiffProg, SpiffAmt, Notes, Approved, MgrNotes, Email);

}

How to add exclamation mark in Grid Bound Column

Hello!

I have a weird problem with my radgrid. In one of my columns (GridBoundColumn), I can't insert the exclamation mark.

It seems like the combination (Shift + 1) is somehow blocked. I can't find anything related to this.

Every other keyboard combination is working. The only way I can add the exclamation mark is by copy paste.

Has anyone encountered this before ? Any help is appreciated!

Thank you!

Disable PostBack on Dropped Item

hi,

I use RadGrid to manipulate row promotion level. I Enabled the user to drag and drop rows to set the drraged item position.

I need to manipulate my datasbase when the dragging finish.

I wish to do this with javascript that invoke WCF service and pass the relevant parameters.

the problem is when the row dropped, the page Posback to server and the user need to wait until the updating to DB will finish.

I only need help to disable this postBack.

(When I use set_cancel method in the droppedEvent Nothing Changed and if I use it in the Drraging event the Dropped Event no Fired at all).

Thanks.

RadButton with two toggle states does not show image

I want to put a button on the page that uses the ConfirmBtn-Grey.jpg image when the page loads, and then when the button is clicked it should display ConfirmBtn-Selected.jpg.

I'm using the following RadButton definition, but not getting any images displayed on my page...

<telerik:RadButton ID="RadButton1" runat="server" ButtonType="ToggleButton" ToggleType="CustomToggle">

<ToggleStates>

<telerik:RadButtonToggleState Selected="true" ImageUrl="../images/ConfirmBtn-Grey.jpg" />

<telerik:RadButtonToggleState ImageUrl="../images/ConfirmBtn-Selected.jpg" />

</ToggleStates>

</telerik:RadButton>

I've checked the paths to my images using Firebug and it's picking them up ok. Have I defined the button incorrectly?

Showing null values in radpivotgrid

I would like to show null values in a pivotgrid to indicate that a sample is misssing. It only shows zero's regardless the setting of IgnoreNullValues. I would expect null, empty or whatever the setting of EmptyValue. What am I missing here? Using UI for ASP.NET AJAX R2 2018 (version 2018.2.516)

<telerik:RadPivotGrid ID="mainpgrid" runat="server"
AllowFiltering ="false"
AllowNaturalSort="false"
AllowPaging ="false"
ShowFilterHeaderZone ="false"
EmptyValue ="(missing sample)" >
<TotalsSettings GrandTotalsVisibility ="None" ColumnsSubTotalsPosition ="None" RowGrandTotalsPosition ="None" />
<Fields >
<telerik:PivotGridColumnField DataField ="SeriesLabel" Caption ="Label" ></telerik:PivotGridColumnField>
<telerik:PivotGridAggregateField DataField ="Value" IgnoreNullValues ="True" Caption ="IgnoreNull" ></telerik:PivotGridAggregateField>
<telerik:PivotGridAggregateField DataField ="Value" IgnoreNullValues ="False" Caption ="DoNotIgnoreNull" ></telerik:PivotGridAggregateField>
<telerik:PivotGridRowField DataField ="UTZDate" Caption ="Date"></telerik:PivotGridRowField>
</Fields>
</telerik:RadPivotGrid>

Code:

Private Sub testpage_Load(sender As Object, e As EventArgs) Handles Me.Load
If Not IsPostBack Then
Dim t As New DataTable
t.Columns.Add("UTZDate")
t.Columns.Add("SeriesLabel")
t.Columns.Add("Value", System.Type.GetType("System.Int32"))

Dim r As DataRow = t.NewRow
r("UTZDate") = Now
r("SeriesLabel") = "Series 0"
r("Value") = DBNull.Value
t.Rows.Add(r)

r = t.NewRow
r("UTZDate") = Now.AddMinutes(5)
r("SeriesLabel") = "Series 0"
r("Value") = 100
t.Rows.Add(r)

Me.mainpgrid.DataSource = t
Me.mainpgrid.DataBind()
End If
End Sub

Check datepicker for no value or null value

I am tring to save information based on if they pick a date back inot the Db. So I am checking on the selectedvalue of the raddatepicker but it gives me this error when I do not have a date in there.

Bassically what I want to do is rotate through my radgrid and if they have picked a date then save information to the DB otherwise just go to the next row. But this error pops if no date is picked.

Nullable object must have a value.

Line 238: If TempDt.SelectedDate.Value > Nothing Then

Protected Sub lnkSaveTemp_Click(sender As Object, e As System.EventArgs) Handles lnkSaveTemp.Click

For Each row As GridDataItem In myRadGrid.Items

Dim Id As Integer = row.GetDataKeyValue("intIssuedId")

Dim TempDt As RadDatePicker = DirectCast(row.FindControl("DatePicker"), RadDatePicker)

Dim TNote As TextBox = DirectCast(row.FindControl("txtNotes"), TextBox)

If TempDt.SelectedDate.Value > Nothing Then

sql = "Update Drat_Issued set dtRecoverTemp = '" & sanitizeString(TempDt.SelectedDate.Value) & "', strNotes = '" & sanitizeString(TNote.Text) & "' where intIssuedId = " & Id

Response.Write(sql)

insertUpdateDelete(sql)

End If

Next

End Sub

Telerik RadComboBox takes lot of time when doing filter in it, using LoadOnDemand mechanism

I have a RadComboBox control inside RadGrid in which Items are loaded using LoadOnDemandmechanism i.e., _ItemRequested() event

All working fine except the 2 issues:
1) There is a significant lag between the time the end-user begins typing and when the filtered items show up. What I observed that the searching in RadcomboBox is done character wise not Word wise.
2) Also, takes time to load data regardless of what value is set in ItemPerRequest property in RadComboBox when using LoadOnDemand.

The maximum items in this RadComboBox can be 20,000+ as well.
User is complaining again and again for the performance issue. Please someone let me know the simplest way of resolving the 2 issues.
I followed below Link (Server Side method), to achieve LoadOnDemand functionality:http://demos.telerik.com/aspnet-ajax/combobox/examples/populatingwithdata/autocompletesql/defaultcs.aspx
If there is no solution to solve the 2 preformance issue then please let me know how to do the searching in RadComboBox, which is inside RadGrid, using LoadOnDemand approach on BUTTON click ?? Will this resolve the 1st Issue ??
Please note that I am new in Telerik. Thanks in advance.
